Claude Code hook that reminds you to go to bed. Every message you send past bedtime, Claude gets told to remind you to wrap up and go to sleep.
A UserPromptSubmit hook that fires on every message you send. If the current time is past bedtime, it injects a bedtime reminder into Claude's context via stdout (exit 0). Claude sees it and reminds you naturally.
Each prompt during bedtime is logged as a violation to ~/.agent-bedtime/violations. As violations accumulate, the hook instructs Claude to get progressively more annoying:
| Violations | Tone |
|---|---|
| 1 | Gentle reminder |
| 2-3 | Firm, mildly disappointed |
| 4-5 | Persistent and direct, keeps responses short, won't engage with new work |
| 6+ | Maximally stubborn, extremely brief, enthusiastically sells you on how great sleep is |
Violations are automatically cleared once wakeup time passes the next day. On clearing, a summary row is appended to ~/.agent-bedtime/history.csv:
date,violations,first_violation,last_violation
2026-02-21,14,2026-02-21 23:57:01,2026-02-22 00:41:30
Add to ~/.claude/settings.json:
{
"hooks": {
"UserPromptSubmit": [
{
"hooks": [
{
"type": "command",
"command": "~/code/tools/agent-bedtime/bedtime-hook"
}
]
}
]
}
}Create ~/.config/agent-bedtime (required):
BEDTIME=23:00
WAKEUP=06:00
Optionally, add a CONTEXT line with extra motivation. This gets included in the hook message, giving Claude more to work with:
CONTEXT="The user has a 7am meeting tomorrow. They're working on a sleep consistency goal this month."
Changes take effect immediately — the file is sourced on every hook invocation, so no restart needed.
